internal error: no expr for path %v

Error message

internal error: no expr for path %v

What it means

In getEnvironmentMember, after locating the member's node under "values", the CLI looks up the corresponding expression via getEnvExpr(esc.Expr{Object: env.Exprs}, path). If no expression is found for a path whose node exists, it returns "internal error: no expr for path %v". This signals an inconsistency between the evaluated properties/expression tree and the definition AST — normally unreachable.

Solutions

1. Retry the command — a concurrent update may have caused the mismatch
2. Update the pulumi CLI to match your ESC service version
3. File a bug with the path and environment definition if it persists

// Verify expr tree and node tree are consistent before rendering
expr, ok := getEnvExpr(esc.Expr{Object: env.Exprs}, path)
if !ok {
    // path mismatch between definition AST and evaluated exprs: re-check env
    return fmt.Errorf("inconsistent state for path %v, re-fetch environment", path)
}

func hasExprAt(exprs esc.Expr, path resource.PropertyPath) bool {
    _, ok := getEnvExpr(exprs, path)
    return ok
}

When it happens

Trigger: Running `pulumi env get <env> <path>` where the YAML node exists under values but the evaluated env.Exprs object has no matching expression entry (e.g. definition changed between evaluation and rendering, or server/client mismatch).

Common situations: Version mismatch between CLI and ESC service; race where the environment was updated mid-command; genuine engine bug.
